māsopavāsairapi śoṣitāṅgā na tāṃ gatiṃ yānti vimuktadehāḥ .
mriyanti revājalapūtakāyāḥ śivārcane keśavabhāvayuktāḥ .. 10.65 ..

Even those who emaciate their limbs with fasts lasting a month do not attain that destination when they abandon their bodies,
which is reached by those who die with their bodies purified by the waters of the Revā, endowed with love for Keśava while worshiping Śiva. (10.65)
